Castelli INSIDER SHORTS, size 3XL. I tried them on over my underwear, then washed them and stored them at home. I bought them intending to wear them under regular clothes without a pad, but I never had the opportunity to use them. - Brand: Castelli - Size: 3XL - Features: Suitable for temperatures up to 40 degrees Celsius, so they seem suitable as inner pants. - Color: Black Thank you for looking.
